  • Publication number: 20220378409
    Abstract: Soft suture anchors are disclosed that can be formed into a pre-strung array with a common working suture. Each anchor includes the common working suture and a soft anchor member that is expandable when implanted. This allows first locking an individual anchor into a bone hole followed by tensioning the suture and independently locking the suture at the anchor. A first anchor is implanted through the tendon and the suture is locked. A second anchor is implanted a selected close distance from the first anchor, the working suture is tensioned between the first and second anchors, and the working suture is locked at the second anchor to create a single suture tensioned and locked stitch between the first and second anchor. This process is repeated for each anchor in the array.

  • Publication number: 20220323199
    Abstract: A system of toggle type suture anchors is disclosed. The plurality of suture anchors is connected in series by a plurality of independently cinchable working suture loops with one working suture loop connecting each pair of anchors in series to form a chain. Each of the suture anchors as connected by working suture loops allows tensioning of the working suture between itself and the prior anchor implanted in the serial string. Further, each anchor includes a loop type locking mechanism to lock the cinchable working suture loop subsequent to tensioning so that the loop remains fixed in size during cyclic loading during joint use. This creates an independently tensioned suture stitch between each implanted suture anchor and the just previously implanted anchor. In total the system as implanted creates a high density, continuous array of anchor-to-anchor stitches for robust securement of soft tissue to bone.

  • Publication number: 20220323200
    Abstract: Methods and apparatus for creating a seam like array of suture stitches joined in series by sequential anchors in bone. The anchors are transtendon implants positioned through the tendon in the original tendon footprint and each array includes four or more anchors. The seam like array extends across at least a portion of the tendon. The stitches can extend generally perpendicular to the direction of the tendon orientation. In rotator cuff repair, the anchors are positioned in the original footprints of the infraspinatus and/or supraspinatus tendons and the seam like array extends in an anterior to posterior direction across the particular tendons torn and repaired. The entire array of anchors can be positioned in the medial half of the original footprints.

  • Publication number: 20220323058
    Abstract: Methods for creating high-density arrays of suture stiches through a tendon into bone for reattachment of a torn tendon, particularly a rotator cuff tendon. The method includes providing a pre-strung plurality of anchors, each anchor having at least one passage therethrough with a continuous length of suture slidably and serially threaded through the at least one passage of each anchor. Each of the anchors further includes a locking assembly for locking the suture within the individual anchor. A first anchor is implanted through the tendon and the suture is locked. A second anchor is implanted a selected close distance from the first anchor, then applying tension to the suture extending from the first anchor and passing through the second anchor the second anchor is locked to create a single suture tensioned and locked stitch between the first and second anchor. This process is repeated for each anchor in the array.

The plurality of suture anchors is connected in series by a single working suture and each of the suture anchors allows tensioning of the working suture between itself and the prior anchor implanted in the serial string. Further, each anchor includes a loop type locking mechanism to lock the working suture in place subsequent to tensioning. This creates an independently tensioned suture stitch between each implanted suture anchor and the just previously implanted anchor. In total the system as implanted creates a continuous array of single anchor to anchor stitches which can be placed close together in high density to form a line or region of stitches for a more robust securement of soft tissue to bone.

  • Publication number: 20220323057
    Abstract: A toggle-type suture anchor that incorporates individual suture tensioning and locking without knot tying. The anchor includes an elongate toggle body having a working suture pre-threaded into a first passage and back up and out a second passage with a length running longitudinally adjacent the side of the anchor. A locking suture loop is pre-threaded into a third passage between the first and second passage and includes a collapsible loop that encircles a portion of the length of suture running longitudinally adjacent the side of the anchor. With the loop open, the working suture can slide through the anchor, however, when the loop is closed the working suture is locked in position to retain tension on the working suture. The anchor can be utilized in a pre-strung connected array of anchors.

  • Publication number: 20220323059
    Abstract: Cartridges configured to hold anchors and associated locking sutures and a common suture used in an array of anchors. A suture anchor array is connected in series by a single working suture and each of the suture anchors allows tensioning of the working suture between itself and the prior anchor implanted in the serial string. Further, each anchor includes a suture lock having a free tail that can be pulled to lock the working suture in place subsequent to tensioning. This creates an independently tensioned suture bridge between each implanted suture anchor and the just previously implanted anchor. The cartridges are configured to securely hold an individual anchor and store the tail of the suture lock, while allowing flossing of anchors along the common suture.

  • Publication number: 20130150418
    Abstract: Method and apparatus are disclosed for applying a therapeutic amount of a non-systemic vasoconstrictor inside the uterus to control abnormal uterine bleeding. The abnormal bleeding can be due to excessive menstrual blood flow, bleeding from a surgical procedure, postpartum bleeding or any other acute or chronic condition. The vasoconstrictor includes topical agents such as an alpha-adrenergic agonist, for example oxymetazoline. The delivery system can include a catheter having means for retaining position of a distal portion within the uterus. A proximal portion can extend outside of the body for coupling to a vasoconstrictor source, or alternatively, the proximal portion can terminate within the vaginal canal and include a docking port for coupling to a source of vasoconstrictor that is inserted therein. In other embodiments, an applicator is disclosed that is positioned in fluid communication with the lumen of the cervix and allows application of a vasoconstrictor therein.
